9WY型牧草网型镇压播种机和9YCB型牧草压槽播种机及其配套使用的9SB—4型牧草种子撒播机最近由中国农业科学院草原研究所研制成功,并通过技术鉴定。这两种牧草播种机属国内首创,具有操作简单、经济实用、保墒抗旱等优点,可广泛用于建立人工草场和改造沙地草场播种牧草之用。网型镇压播种机(主要技术参数见附表)采用国内首创的网型镇压播种法,可进行翻压、播种、耕翻等操作,使种子与土壤紧密接触,保证种子着床实,发芽率高,并给种子覆虚土,以切断土壤毛细营,防止水份大量蒸发,起到保墒抗旱的作用。
9WY pasture mesh suppression planter and 9YCB type pasture trough planter and its supporting the use of 9SB-4 forage seed spreader recently developed by the Chinese Academy of Agricultural Sciences Grassland Institute, and passed the technical appraisal. These two kinds of forage planter is the first in China, with the advantages of simple operation, economical and practical, moisture and drought resistance, etc. It can be widely used to establish artificial grassland and rehabilitate grassland to sow pasture. Mesh-type repressing seeder (main technical parameters, see attached table) Using the first domestic net-type repressing sowing method, can be pressure, sowing, plowing and other operations, the seeds and soil in close contact with the seeds to ensure the seed, germination rate High, and cover the soil to the seed, in order to cut off the capillary camp soil, to prevent a large number of evaporation of water, played the role of moisture and drought.
